9 Claims. (Cl. 116-117) This invention pertains to liquid dispensing apparatus and more particularly to sight gauges for liquid dispensing apparatus so constructed and arranged as to be visible from any position around the liquid dispensing apparatus.

An object of the invention is to provide a liquid dispensing apparatus having connected sight gauges visible from any position around the apparatus.

Another object is to provide a sight gauge which is inexpensive to make and maintain and fullls all conditions of manufacture and service.

A further object is to provide a sight gauge which is readily accessible and clearly indicates the passage of dispensed liquid through the liquid dispensing apparatus.

A yet further object is to provide a sight gauge which readily drains when the liquid level in the liquid dispensing apparatus falls, yet one which eXpels air therefrom when the liquid level is raised as by dispensing operation.

With these and various other objects in view, the invention may consist of certain novel features of construction and operation as will be more fully described and particularly pointed out in the specification, drawings and claims appended hereto. Y

Figure 8 is a vertical elevation partly in section through the assembly shown in Figure 6,

the same being taken substantially in the plane as indicated by the line 8 8 of Figure 6, one of the sight gauge glasses being shown in assembly but just prior to application to the housing.

Referring rst of all more particularly to the liquid dispensing apparatus and sight gauge assembly illustrated in Figures 1 to 5 inclusive, the liquid dispensing apparatus I consists essentially of the casing l2 supported on the pedestal I4. The pump I6 is supported within the casing l2, the suction side of said pump being connected through the pipe i8 to the source of liquid supply 26, a suitable foot valve 22 being provided to prevent drain-back of the liquid While the apparatus is inoperative. The pump is provided with the pulley 24 connected as by means of the belt .26 to the pulley 28 provided on the motor 30, the motor being controlled through a suitable switch (not shown) connected to the switch control member 32 pivoted as at 34 to the casing adjacent the hose hook support 36.

The loutlet side of the pump 16 is connected to the inlet side of the meter 36 through the pipe 40. The meter is shown as of the displacement type, the outlet side of said meter being connected through the piping 42, the piping 42 being provided withfthe tting 44 adapted to be secured as at 46 to the sight gauge housing 48. The outlet side of the housing 48 is connected through the piping 50 to the fitting 52 to which the usual dispensing hose (not shown) is connected, the opposite end of said hose being connected in the usual manner to the dispensing nozzle 54. The nozzle 54 includes the nozzle guardi 56 shown supported on the hose support 36 and Within the nozzle guard there is pivoted the operating lever B adapted to control operation of the dispensing valve 66. The nozzle end 62 is shown extending into the guard housing 64 to prevent unauthor" ized dispensing operation when the pump is locked out of use. v

The meter 38 is provided with the usual rotatable valve to which the meter shaft 66 is secured,

the upper end of said meter shaft being adapted to operate the register and computing assembly 68. In the form of construction shown, the

register or clock assembly is of the computing' 'I'he register mechanism is provided with the set-back shaft 14 adapted to be controlled by the reset crank 16, the opposite end of said shaft having cooperative relation to reset interlocking mechanism indicated generally at 18, said mechanism permitting or preventing operation of the switch control member 32 and consequently permitting or preventing dispensing of the liquid until the register has been reset to zero.

The usual air separator may likewise be connected to the meter on the inlet side thereof, the released air being exhausted at a high point in the liquid dispensing apparatus through the piping 82.

Referring now more particularly to the sight gauge assembly, the housing 48 consists essentially of the opposite spaced side walls 84 and 86, supporting brackets 88 and 90 being provided thereon for receiving suitable securing means for fastening the housing to the casing or corner posts thereof. Spaced iront walls 92 and 94 are provided, each of said walls having offset portions 96 and 98 suitably threaded as at |00 and |02 adjacent the ends thereof. The housing is closed by means of the upper and lower walls |05 and |04 connected by the center Wall |06 shown as of cylindrical construction, permitting the passage of wiring and the like into the upper portion of the liquid dispensing apparatus should such be desired.

The side'wall 84 `is provided with the inlet opening |08 andthe outlet opening ||0 separated by means of the dividing wall I2 extending from the center wall |06 to the outer wall 84. The housing is also provided with oppositely extending radial ribs ||4 and ||6 extending between the upper and lower walls and integral therewith and extending from the center wall outwardly to the oiset portions 96 and 98 respectively but` terminating short of the ends of said offset portions. On each of the offset portions 96 and 98 there is seated a substantially dome shaped transparent member ||8 and |20 forming a socalled bulls eye sight gauge, the members ||8 and |20 being formed of material such as glass and being flanged as at |22 and |24 and seated on the offset members 96 and 98 respectively, through a gasket such as a cork gasket |26 and |28 to which some material such as litharge or red lead may be applied,

The members 8 and |20 are retained in operative position by means of a circular apertured nut or collar |30 and |32 ilanged as at |34 and |36 to overlie the flanges |22 and |24 of the sight gauge, said collars being threaded as at |38 and |40 to engage the threads |00 and |02 respectively and Aprovided with the lugs |0| and |03 to receive a suitable wrench to facilitate application and removal of said collar. The joint between the anges |34 and |22, and the flanges |36 and |24 is maintained tight through gaskets |44 likewise liquid-proofed by litharge or the like. A portion of each of the ends of offset portions 96 and 98 is circular in cross-section and Vextends below the bottom wall |04 of the housing such as shown at |46 and |48, and the spinner housings thus formed are preferably threaded as at |50 and |52 for receiving suitable piping |54 and |56 extending from a low point in the spinner housings to the fitting 52 whereby if the liquid level should drop for any reason such as a leaking foot valve or if the piping should be drained, the sight gauge will immediately 4'completely drain so that any existving fault'can be promptly remedied.

preferably i rotatable sleeves |66 and |68 seated on the inner 5 and outer bearings or washers |10, |12, |14 and |16, and suitably secured as by means of pins |18 and |80. The inner portions of the sleeves |66 and |68 are provided with the vanes |82 and |84,

providing substantially a turbine, and the outer 10 ends of said spindles are provided with deflected vanes |86 and |88 forming spinners which are visible through the members 8 and |20;

The bottom wall of the housing 48 adjacent the ribs ||4 and ||6 may also be apertured as at l5 |90 and |92, and glass members |94 and |96 may be secured thereto as by means of the clamping rings |98 and 200 suitably secured as at 202 andl 204 for closing the housing. The litharged gaskets 206 and 208 are interposed between the re- 20 spective glasses and the adjacent bottom wall of the housing and the litharged gaskets 2|0 and 2|2 are interposed between the respective rings |98 and 200 of the adjacent glass. The purpose of this aperture is to permit light to shine 25 through the dispensed liquidso that at night the spinners |86 and |88 will be illuminated to clearly indicate thel flow. A suitable electric bulb may be provided as at the -socket 2| 4 connected to the conduit -2|6 and controlled by the switch 30 2|8, the conduit being connected to a suitable source ofelectric supply (not shown).

Assuming the register 12 to be set to zero, and the nozzle 54 removed from the support, in order to-dispense liquid it is only necessary to raise the 35 switch control member 32 starting the motor 30. Starting the'motor 30 will cause the pump vI6 to draw liquid from the source of liquid supply, liquid passing through the meter 38, the piping 42 and into the inlet |08 of the sight gauge hous- 40 ing. Liquid introduced through the inlet |08 will pass around the rib ||6 rotating the turbine f |84 and causing rotation of the spinner |88. The liquid will then continue around the center wall |06 and around the rib |'|4 causing rotation of 45 the turbine |82 and consequently the spinner |86. The liquid will then pass outwardly of the outlet ||0 through the connection .50 out the dispensing hose and nozzle, it being assumed that the nozzle valve has been kept open by 5o means of the operating lever 58. With this assembly it will be appreciated that repairs can. readily bemade as the members ||8 and |20 canbe readily removed by simply removing the associated collars |30 and |32 facilitating clean- 55 ing out of the sight gauge.

While the spinner housings have been illustrated in a serieslcircuit of the liquid being measured, it will be understood, of course, that other circuits for accomplishing similar results may 60 be utilized.

Referring now more particularly to the construction illustrated in Figures 6, '7` and 8, the corner posts 220 of the pump casing l2 are provided adjacent the upper portion thereof with the 55 brackets 222, to which the space supports 224 and 226 are secured at opposite sides of the pump. The transversely extending sight gauge housing 228 is disposed to be supported on the members 224 and 226, said housing consisting essentially 70 of the manifold 230 provided with the downwardly disposed inlet 232 adapted to receive liquid from the upwardly extending discharge pipe, such as the pipe 42 shown in Figure 1. The inlet 232 communicates with the turbine or rotor 75 housing 234, said housing communicating with the substantially horizontally extending discharge member 236 adapted to be connected to the pipe 5B which in turn is connected to the tting 52 to which the discharge hose is connected. The manifold 239 is provided with the end wall 236 which is connected as by the threads 2d@ to the outwardly extending tube 242 threaded as at 26d to the spinner housing 256, said housing corresponding to the olset portion 98 of the rst mentioned device, being provided with the shoulders 248 disposed adjacent the threaded end portion 250. 'Ihe outer end of the manifold 239 is provided with the shoulders 252 corresponding to the shoulders 248 and the threaded end portion 254 corresponding to the threaded portion 250.

The turbine or rotor 256 is disposed'in the chamber or housing 234 and is mounted on the transversely extending shaft 258, said shaft being journaled as at 250 in the spider 262 provided in the tube 2&2 adjacent the end wall 238. One end' of the shaft extends into the casing 24d and through the apertured stabilizing disc 264i which also acts as a bearing for the shaft as at 266.

The outer end of said shaft is spaced outwardly.

of the end of said casing and is provided with the spinner 268 yprovided with the deected vanes 279, the opposite end of the vshaft extending through the apertured stabilizing disc 272 providing the journal 213 and is provided adjacent the end thereof with the spinner 2l@ likewise provided with the deilected vanes 276.

The ends of the housing 216` and the housing 228 are adapted to be closed by the domed transparent members 219 and 220, said members being similar to the members llt and l2il. The members 2l@ and 280 are flanged as at 262 and 286 and are adapted to be held in position by means of the collars 226 and 28d provided with the lugs 290 and 292 to facilitate the assembly. The gasket 29d is interposed between each domed member and backing nut 296 which is threaded on the respective collars 2% and 228 for assembling the members 273 and 28@ with their respective collars, gasket 293 being interposed between the ilanges 282 and 23d and the respective inwardlyextending flanges 3M and 3il2 of the respective collars. With this assembly breakage of the transparent members is prevented in assembling the transparent members with the housing, particularly in field repair work, as the unit is applied as a whole as shown at the left of Figure 8, thereby relieving the flanges of the domed members from strain. The whole assembly of the transparent member, the respective collar and the backing nut are then threaded in place on the threads 25@ and 25d, suitable gaskets 304 and 306 being interposed between the backing nut and the adjacent hous v ing and the collar and the adjacent housing. As

before, alitgaskets are applied with liquid-proofing, as litharge, or other suitable material.

As the housing M6 is connected to the housing 228 through the tube 262 in order to exhaust the air or vapor from the sight gauge member 2l@ to permit the ow of yliquid thereto, a iitting 3&8 is tapped into the housing 246 adjacent a high point therein, and said fitting 302 is connected to the fitting 340 by means of the tube m2. The fitting 3m is provided with a tube 3M extending through the boss 3W into the outlet` member 23% so as to extend into the path of discharge whereby liquid passing outwardly tends to draw the air from the housing 246, thus facilitating the passage of liquid into 'the sight gauge member 218. The turbine casing 234 is likewise provided with the fitting 3l8 adjacent a low point thereof, preferably below the rotor, and the tube 320 is connected through the tting 322 to the member 52. Thus, should the bevel of liquid fall in the device due to leakyv foot valve or the like, the sight gauge will be drained, indicating that such a condition exists.

In operation of this formof the device, liquid enters the turbine housing through the inlet 232 revolving the turbine 256, the liquid then passing outwardly through the outlet 236, the discharge pipe Eil, the fitting 52 and the discharge hose in a manner already described. Rotation of the turbine 255 causes rotation of the shaft 258, thus rotating the spinners 268 and 2N, thus indicating that liquid is being dispensed, it being understood that liquid will completely fill the transparent members in the sight gauge.

Illumination may be effected externally of the device through suitable lighting effects or in- Wardly of the device through suitable glass means such as shown at i913 and H96 of Figure 4, this having been omitted in Figures 6 and 8 as a mat-y ter of convenience.

It is to be understood that we do not wish to be limited by the'exact embodiments of thedevice shown, which are merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
